This coat is my first of many "puffy" coats to come. 6'2" 225 and the XL is just the ticket! By itself or as an isulattive layer the Nano gets the job done. Also, the electric color will garner unsolicited comments. I just smile as I know that i'm cooler or "warmer" than they are.
I bought this coat for my wife. I bought it in a mens' cause she is taller than most women. The fit is GREAT she says. It's warm, stylish, and comfy. The only knock is that she wishes it had an exterior pocket like the Marmot it replaced.
